为提升客舱布局设计效率及面向民机客舱快速仿真设计系统提供技术支撑，提出了一种民机客舱布局量化设计模型。该模型面向工效学设计需求，以座椅排距、座椅排数、各级客舱舱段长度等作为设计变量，构造了舒适性、安全性、经济性三类目标函数，实现了客舱边界限制、人机空间耦合关系、适航安全性要求等约束条件的量化描述。分别以双通道宽体干线客机、单通道窄体干线客机和支线客机为应用算例，对所提模型的可用性进行了计算验证。结果表明:所提模型可适用于多种机型的客舱布局设计，能够提供多个满足舒适性、安全性、经济性等多样化工效学设计指标的量化设计方案，并可给出各类指标进一步的优化途径。所提模型在一定程度上实现了民机客舱布局量化设计，为概念设计阶段客舱布局快速设计和多方案比较提供了一种新的方法，同时也可作为航空公司客舱布局选型的定量化辅助决策工具。 

Quantitative design model of civil aircraft cabin layout for ergonomics

To improve layout design efficiency and provide technical support for the rapid simulation design system of civil aircraft cabin, a quantitative design model for civil aircraft cabin layout is proposed. The ergonomic demand-oriented model took seat row distance, seat row number and cabin section length as design variables, and constructed three objective functions, which are comfort, economy and safety. The constraints were quantitatively represented in the model, including cabin boundary restriction, man-machine space coupling relationship, and airworthiness safety requirements. Model applicability was verified by taking the dual-aisle wide-body, single-aisle narrow-body, and regional airliner as analytical examples. The results show that the model can be applied to various types of cabin layout design by providing multiple quantitative design schemes meeting ergonomic design requirements. Optimization approaches for various types of indices can also be revealed in the model. It indicates that the quantitative design model could be a new adaptive method for the rapid design and the schemes comparison in the conceptual design stage and a quantitative assistant decision-making tool for the selection of airline passenger cabin layout.
